Oil Pressure Sender: Description and Operation
Switch-Oil Pressure
OPERATION
The oil pressure sensor uses two circuits. They are:
-
A signal to the PCM relating to engine oil pressure
-
A sensor ground through the PCM's sensor return
The oil pressure sensor returns a voltage signal back to the PCM relating to engine oil pressure. This signal is then transferred (bussed) to the instrument
panel on a CCD bus circuit to operate the oil pressure gauge and the check gauges lamp. Ground for the sensor is provided by the PCM through a
low-noise sensor return.
